Hypoallergenic

One of my dogs has to have hypoallergenic food which is quite expensive but I have found somewhere where it's 10 pounds cheaper per bag, it says this is for working dogs. Will my dog be able to eat this?

As far as I know food for working dogs food gives them extra strength they need to work so may make your gain wait, but I'm no expert, hopefully someone will be along shortly to offer more help

It's designed to give extra energy that would be burnt off by a working dog, so I wouldn't have thought it would be a good thing for a domestic dog  But again I'm no expert!
